    What is missing from this CDC school reopening priority list? Airborne virus guidance! Like almost nothing in 33 page document on ventilation except 1 paragraph on open the windows, but only if feasible. Ventilation should be #2 behind masks! #COVID19 https://www.cdc.gov/coronavirus/2019-ncov/downloads/community/schools-childcare/K-12-Operational-Strategy-2021-2-12.pdf …pic.twitter.com/WA2T2yDkVN

        2) Notably absent from new CDC guidance was ventilation. In one short paragraph, CDC suggested schools open windows & doors to increase circulation, but said they should not be “if doing so poses a safety risk or a health risk.” #COVID19https://www.nytimes.com/2021/02/12/health/school-reopenings-cdc.amp.html?referringSource=articleShare#click=https://t.co/lhDggiLYYh …

        3) “C.D.C. gives lip service to ventilation in its report, and you have to search to find it,” said @j_g_allen, an expert on building safety at the Harvard T.H. Chan School of Public Health in Boston. “It’s not as prominent as it should be.”

        4) The section on ventilation does link to more information online. But all of that is buried, relative to a misguided emphasis on cleaning surfaces like outdoor playground equipment, said Linsey Marr, an expert in airborne transmission of viruses at Virginia Tech...

        5) “I think the balance is incorrect in putting so much emphasis on cleaning surfaces and almost no emphasis on cleaning the air, given what we know about how the virus spreads,” Marr said.

        6) VENTILATION is key. Both ventilation and masks needed to reduce risk indoors. But most buildings not ventilated well enough.pic.twitter.com/qhz8cs0grH

        7) How is aerosol different from large droplets? aerosol study indicates that coronavirus is persistent and stable for many hours. Typical air exchange every 20 min to 4 hrs, depending on ventilation. #COVID19pic.twitter.com/dUUjHriWge

        8) Key is ventilation. 🇯🇵 assumed it was airborne from the beginning. Here is how to ventilate your school classrooms if unable to open window but only have 1 door — use two fans near doorway. #COVID19pic.twitter.com/ZiOdMG2GPs

        📍FAUCI SAYS THE CORONAVIRUS IS AIRBORNE—it’s not official until the Fauci sings. And Dr Fauci has come out strongly: “Bottomline, there’s much more aerosol 💨 than we thought”. #COVID19 Moreover, #SARSCoV2 also found in: 📌Stool 📌Blood 📌Semen 📌Eye secretions ➡️ Thread🧵 pic.twitter.com/ie1BGkZODc

        13) I don’t know how you can just say indoor sports is safe as long as 6 feet. Even outdoors 6 feet isn’t without risk. NFL 🏈 also has done a lot of studies on this—they know 6 feet isn’t enough.pic.twitter.com/IjGXQJbDD0
